where p is 4 in the case of pyridinyl and 3 in the case of pyrazinyl, pyrimidinyl, and pyridazinyl, and R⁵ are independently H, halo, lower alkyl, lower alkoxy, lower alkenyl, lower alkynyl, haloalkyl, haloalkoxy, NO₂, CN, lower alkoxycarbonyl and lower alkyl-SO_(q) and q is an integer from 0 to 2.

Throughout this document, all temperatures are given in degrees Celsius, and all percentages are weight percentages unless otherwise stated.

The terms “alkyl”, “alkenyl” and “alkynyl”, as well as derivative terms such as “alkoxy” and “alkylthio”, as used herein, include within their scope straight chain, branched chain and cyclic moieties. The terms “alkenyl” and “alkynyl” are intended to include one or more unsaturated bonds.

The term “halo” refers to F, Cl, Br, and I atoms.

The term “lower alkyl” refers to C₁ to C₆ straight hydrocarbon chains and C₃ to C₆ branched and cyclic hydrocarbon groups.

The terms “lower alkenyl” and “lower alkynyl” refer to C₂ to C₆ straight hydrocarbon chains and C₃ (or C₄ in the case of lower alkynyl) to C₆ branched hydrocarbon groups containing at least one unsaturated bond.

The terms “lower alkoxy” and “lower alkylthio” refer to O-lower alkyl and S-lower alkyl groups.

In the present invention, whenever multiple substituents are independently selected it is to be understood that they are selected so as to be sterically compatible with each other. Steric compatibility refers to the absence of steric hindrance as this term is defined in The Condensed Chemical Dictionary, 7th edition, Reinhold Publishing Co., N.Y. page 893 (1966), which definition is as follows:

-   -   steric hindrance. A characteristic of molecular structure in         which the molecules have a spatial arrangement of their atoms         such that a given reaction with another molecule is prevented or         retarded in rate.         Steric compatibility is characterized by substituents whose         physical bulk does not require confinement within volumes         insufficient for the exercise of their normal behavior as         discussed in D. J. Cram and G. Hammond, Organic Chemistry 2nd         edition, McGraw-Hill Book Company, N.Y. page 215 (1964).

Detailed information regarding pests may be found in the “Handbook of Pest Control—The Behavior, Life Histroy, and Control of Household Pests” by Arnold Mallis, 9^(th) Edition, copyright 2004 by GIE Media Inc, which is expressly incorporated by reference herein.

The present invention contemplates all vehicles by which the composition of the present invention can be formulated for delivery and use as a pesticide composition, including solutions, suspensions, emulsions, wettable powders and water dispersible granules, emulsifiable concentrates, granules, dusts, baits, and the like. Compositions suitable for administration to vertebrates or man include preparations suitable for oral, parenteral, percutaneous, e.g. pour-on, or topical administration.

Compositions for oral administration comprise one or more of the compounds of general formula I in association with pharmaceutically acceptable carriers or coatings and include, for example, tablets, pills, capsules, pastes, gels, drenches, medicated feeds, medicated drinking water, medicated dietary supplements, slow-release boluses or other slow-release devices intended to be retained within the gastro-intestinal tract. Any of these may incorporate active ingredient contained within microcapsules or coated with acid-labile or alkali-labile or other pharmaceutically acceptable enteric coatings. Feed premixes and concentrates containing compounds of the present invention for use in preparation of medicated diets, drinking water or other materials for consumption by animals may also be used.

Compositions for parenteral administration include solutions, emulsions or suspensions in any suitable pharmaceutically acceptable vehicle and solid or semisolid subcutaneous implants or pellets designed to release active ingredient over a protracted period and may be prepared and made sterile in any appropriate manner known to the art.

Compositions for percutaneous and topical administration include sprays, dusts, baths, dips, showers, jets, greases, shampoos, creams, wax-smears, or pour-on preparations and devices (e.g. ear tags) attached externally to animals in such a way as to provide local or systemic arthropod control

Typically, formulations for application to plants or soil are applied following dilution of the concentrated formulation with water as aqueous solutions, suspensions or emulsions, or combinations thereof. Such solutions, suspensions or emulsions are produced from water-soluble, water-suspended or water-suspendable, water-emulsified or water-emulsifiable formulations or combinations thereof which are solids, including and usually known as wettable powders or water dispersible granules; or liquids including and usually known as emulsifiable concentrates, aqueous suspensions or suspension concentrates, and aqueous emulsions or emulsions in water, or mixtures thereof such as suspension-emulsions. As will be readily appreciated, any material to which this composition can be added may be used, provided they yield the desired utility without significant interference with the desired activity of the pesticidally active ingredients as pesticidal agents and improved residual lifetime or decreased effective concentration is achieved.

Wettable powders, which may be compacted to form water dispersible granules, comprise an intimate mixture of one or more of the pesticidally active ingredients, an inert carrier and surfactants. The concentration of the pesticidally active ingredient in the wettable powder is usually from about 10 percent to about 90 percent by weight based on the total weight of the wettable powder, more preferably about 25 weight percent to about 75 weight percent. In the preparation of wettable powder formulations, the pesticidally active ingredients can be compounded with any finely divided solid, such as prophyllite, talc, chalk, gypsum, Fuller's earth, bentonite, attapulgite, starch, casein, gluten, montmorillonite clays, diatomaceous earths, purified silicates or the like. In such operations, the finely divided carrier and surfactants are typically blended with the compound(s) and milled.

Emulsifiable concentrates of the pesticidally active ingredient comprise a convenient concentration, such as from about 10 weight percent to about 50 weight percent of the pesticidally active ingredient, in a suitable liquid, based on the total weight of the concentrate. The pesticidally active ingredients are dissolved in an inert carrier, which is either a water miscible solvent or a mixture of water-immiscible organic solvents, and emulsifiers. The concentrates may be diluted with water and oil to form spray mixtures in the form of oil-in-water emulsions. Useful organic solvents include aromatics, especially the high-boiling naphthalenic and olefinic portions of petroleum such as heavy aromatic naphtha. Other organic solvents may also be used, such as, for example, terpenic solvents, including rosin derivatives, aliphatic ketones, such as cyclohexanone, and complex alcohols, such as 2-ethoxyethanol.

Emulsifiers which can be advantageously employed herein can be readily determined by those skilled in the art and include various nonionic, anionic, cationic and amphoteric emulsifiers, or a blend of two or more emulsifiers. Examples of nonionic emulsifiers useful in preparing the emulsifiable concentrates include the polyalkylene glycol ethers and condensation products of alkyl and aryl phenols, aliphatic alcohols, aliphatic amines or fatty acids with ethylene oxide, propylene oxides such as the ethoxylated alkyl phenols and carboxylic esters esterified with the polyol or polyoxyalkylene. Cationic emulsifiers include quaternary ammonium compounds and fatty amine salts. Anionic emulsifiers include the oil-soluble salts (e.g., calcium) of alkylaryl sulfonic acids, oil-soluble salts of sulfated polyglycol ethers and appropriate salts of phosphated polyglycol ether.

Representative organic liquids which can be employed in preparing emulsifiable concentrates are the aromatic liquids such as xylene, propyl benzene fractions; or mixed naphthalene fractions, mineral oils, substituted aromatic organic liquids such as dioctyl phthalate; kerosene; dialkyl amides of various fatty acids, particularly the dimethyl amides; and glycol ethers such as the n-butyl ether, ethyl ether or methyl ether of diethylene glycol, and the methyl ether of triethylene glycol and the like. Mixtures of two or more organic liquids may also be employed in the preparation of the emulsifiable concentrate. Surface-active emulsifying agents are typically employed in liquid formulations and in an amount of from 0.1 to 20 percent by weight based on the combined weight of the emulsifying agents. The formulations can also contain other compatible additives, for example, plant growth regulators and other biologically active compounds used in agriculture.

Aqueous suspensions comprise suspensions of one or more water-insoluble pesticidally active ingredients dispersed in an aqueous vehicle at a concentration in the range from about 5 to about 50 weight percent, based on the total weight of the aqueous suspension. Suspensions are prepared by finely grinding one or more of the pesticidally active ingredients, and vigorously mixing the ground material into a vehicle comprised of water and surfactants chosen from the same types discussed above. Other components, such as inorganic salts and synthetic or natural gums, may also be added to increase the density and viscosity of the aqueous vehicle. It is often most effective to grind and mix at the same time by preparing the aqueous mixture and homogenizing it in an implement such as a sand mill, ball mill, or piston-type homogenizer.

Aqueous emulsions comprise emulsions of one or more water-insoluble pesticidally active ingredients emulsified in an aqueous vehicle at a concentration typically in the range from about 5 to about 50 weight percent, based on the total weight of the aqueous emulsion. If the pesticidally active ingredient is a solid it must be dissolved in a suitable water-immiscible solvent prior to the preparation of the aqueous emulsion. Emulsions are prepared by emulsifying the liquid pesticidally active ingredient or water-immiscible solution thereof into an aqueous medium typically with inclusion of surfactants that aid in the formation and stabilization of the emulsion as described above. This is often accomplished with the aid of vigorous mixing provided by high shear mixers or homogenizers.

The compositions of the present invention can also be granular formulations, which are particularly useful for applications to the soil. Granular formulations usually contain from about 0.5 to about 10 weight percent, based on the total weight of the granular formulation of the pesticidally active ingredient(s), dispersed in an inert carrier which consists entirely or in large part of coarsely divided inert material such as attapulgite, bentonite, diatomite, clay or a similar inexpensive substance. Such formulations are usually prepared by dissolving the pesticidally active ingredients in a suitable solvent and applying it to a granular carrier which has been preformed to the appropriate particle size, in the range of from about 0.5 to about 3 mm. A suitable solvent is a solvent in which the compound is substantially or completely soluble. Such formulations may also be prepared by making a dough or paste of the carrier and the compound and solvent, and crushing and drying to obtain the desired granular particle.

Dusts can be prepared by intimately mixing one or more of the pesticidally active ingredients in powdered form with a suitable dusty agricultural carrier, such as, for example, kaolin clay, ground volcanic rock, and the like. Dusts can suitably contain from about 1 to about weight percent of the compounds, based on the total weight of the dust.

The formulations may additionally contain adjuvant surfactants to enhance deposition, wetting and penetration of the pesticidally active ingredients onto the target site such as a crop or organism. These adjuvant surfactants may optionally be employed as a component of the formulation or as a tank mix. The amount of adjuvant surfactant will typically vary from 0.01 to 1.0 percent by volume, based on a spray-volume of water, preferably 0.05 to 0.5 volume percent. Suitable adjuvant surfactants include, but are not limited to ethoxylated nonyl phenols, ethoxylated synthetic or natural alcohols, salts of the esters of sulfosuccinic acids, ethoxylated organosilicones, ethoxylated fatty amines and blends of surfactants with mineral or vegetable oils.

The formulations may optionally include combinations that contain one or more other pesticidal compounds. Such additional pesticidal compounds may be fungicides, insecticides, nematicides, miticides, arthropodicides, bactericides or combinations thereof that are compatible with the compounds of the present invention in the medium selected for application, and not antagonistic to the activity of the present compounds. Accordingly, in such embodiments, the other pesticidal compound is employed as a supplemental toxicant for the same or for a different pesticidal use. The compounds of the present invention, and the pesticidal compound in the combination can generally be present in a weight ratio of from 1:100 to 100:1.

The compounds disclosed in this invention can be in the form of pesticidally acceptable acid addition salts.

By way of non-limiting example, an amine function can form salts with hydrochloric, hydrobromic, sulfuric, phosphoric, acetic, benzoic, citric, malonic, salicylic, malic, fumaric, oxalic, succinic, tartaric, lactic, gluconic, ascorbic, maleic, aspartic, benzenesulfonic, methanesulfonic, ethanesulfonic, hydroxymethanesulfonic, and hydroxyethanesulfonic acids.

Additionally, by way of non-limiting example, an acid function can form salts including those derived from alkali or alkaline earth metals and those derived from ammonia and amines. Examples of preferred cations include sodium, potassium, magnesium, and aminium cations.

The salts are prepared by contacting the free base form with a sufficient amount of the desired acid to produce a salt. The free base forms may be regenerated by treating the salt with a suitable dilute aqueous base solution such as dilute aqueous NaOH, potassium carbonate, ammonia, and sodium bicarbonate. As an example, in many cases, a pesticide is modified to a more water soluble form e.g. 2,4-dichlorophenoxy acetic acid dimethyl amine salt is a more water soluble form of 2,4-dichlorophenoxy acetic acid, a well known herbicide.

The compounds disclosed in this invention can also form stable complexes with solvent molecules that remain intact after the non-complexed solvent molecules are removed from the compounds. These complexes are often referred to as “solvates”.

Certain compounds disclosed in this document can exist as one or more stereoisomers. The various stereoisomers include geometric isomers, diastereomers, and enantiomers. Thus, the compounds disclosed in this invention include racemic mixtures, individual stereoisomers, and optically active mixtures. It will be appreciated by those skilled in the art that one stereoisomer may be more active than the others. Individual stereoisomers and optically active mixtures may be obtained by selective synthetic procedures, by conventional synthetic procedures using resolved starting materials, or by conventional resolution procedures.

The compounds of the present invention can also be combined with other agricultural fungicides to form fungicidal mixtures and synergistic mixtures thereof. The fungicidal compounds of the present invention are often applied in conjunction with one or more other fungicides to control a wider variety of undesirable diseases.

The compounds of the present invention may have broad ranges of efficacy as fungicides and insecticides. The exact amount of the active material to be applied is dependent not only on the specific active material being applied, but also on the particular action desired, the pathogen or pest to be controlled, and the stage of growth thereof, as well as the part of the plant, animal or other medium to be contacted with the compound. Thus, all the compounds, and formulations containing the same, may not be equally effective at similar concentrations or against the same pathogen and pest species.

The compounds are effective in use with plants in a phytologically acceptable amount. The term “phytologically acceptable amount” refers to an amount of a compound that kills or inhibits the pest or plant disease for which control is desired, but is not significantly toxic to the plant. This amount will generally be from about 0.1 to about 1000 ppm (parts per million), with 1 to 500 ppm being preferred.

The exact concentration of compound required varies with the pest or disease to be controlled, the type of formulation employed, the method of application, the particular plant or animal species, climate conditions, and the like. For fungicides, dilution and rate of application will depend upon the type of equipment employed, the method and frequency of application desired and diseases to be controlled, but the effective amount is usually from about 0.01 kilogram (kg) to about 20 kg, of active ingredient (a.i.) per hectare (ha). As a foliar fungicide, a compound of the present invention is usually applied to growing plants at a rate of about 0.1 to about 5 and preferably from about 0.125 to about 0.5 kg per hectare.

As a seed-applied fungicide, the amount of toxicant coated on the seed is usually at a dosage rate of about 0.1 to about 250 grams (g) and preferably from about 1 to about 60 g per 100 kilograms of seed. As a soil fungicide, the chemical can be incorporated in the soil or applied to the surface of the soil or a rice nursery box usually at a rate of about 0.1 to about 5 kg per hectare.

The actual amount of insecticide or miticide to be applied to loci of pests is generally not critical and can readily be determined by those skilled in the art. In general, concentrations from about 0.01 grams of pesticide per hectare to about 5000 grams of pesticide per hectare are expected to provide good control.

The locus to which a pesticide is applied can be any locus inhabited by an pest, for example, vegetable crops, fruit and nut trees, grape vines, ornamental plants, domesticated animals, the interior or exterior surfaces of buildings, and the soil around buildings. Controlling pests generally means that pest populations, activity, or both, are reduced in a locus. This can come about when: pest populations are repulsed from a locus; when pests are incapacitated, partially or completely, temporarily or permanently, in or around a locus; or pests are exterminated, in whole or in part, in or around a locus. Of course a combination of these results can occur. Generally, pest populations, activity, or both are desirably reduce more than fifty percent, preferably more than 90 percent, even more preferably 99 percent.

Generally, with baits, the baits are placed in the ground where, for example, termites can come into contact with the bait. Baits can also be applied to a surface of a building, (horizontal, vertical, or slant, surface) where, for example, ants, termites, cockroaches, and flies, can come into contact with the bait.

Because of the unique ability of the eggs of some pests to resist pesticides repeated applications may be desirable to control newly emerged larvae.

Systemic movement of pesticides in plants may be utilized to control pests on one portion of the plant by applying the pesticides to a different portion of the plant, or to a location where the root system of a plant can uptake pesticides. For example, control of foliar-feeding insects can be controlled by drip irrigation or furrow application, or by treating the seed before planting.

Seed treatment can be applied to all types of seeds, including those from which plants genetically transformed to express specialized traits will germinate. Representative examples include those expressing proteins toxic to invertebrate pests, such as Bacillus thuringiensis or other insecticidal toxins, those expressing herbicide resistance, such as “Roundup Ready” seed, or those with “stacked” foreign genes expressing insecticidal toxins, herbicide resistance, nutrition-enhancement or any other beneficial traits. Furthermore, such seed treatments with the invention disclosed in this document can further enhance the ability of a plant to better withstand stressful growing conditions. This results in a healthier, more vigorous plant, which can lead to higher yields at harvest time.

It should be readily apparent that the invention may be used with plants genetically transformed to express specialized traits, such as Bacillus thuringiensis or other insecticidal toxins, or those expressing herbicide resistance, or those with “stacked” foreign genes expressing insecticidal toxins, herbicide resistance, nutrition-enhancement or any other beneficial traits. An example of such a use is spraying such plants with the invention disclosed in this document.

The invention disclosed in this document may be suitable for controlling endoparasites and ectoparasites in the veterinary medicine sector or in the field of animal keeping. Compounds according to the invention are applied here in a known manner, such as by oral administration in the form of, for example, tablets, capsules, drinks, granules, by dermal application in the form of, for example, dipping, spraying, pouring on, spotting on, and dusting, and by parenteral administration in the form of, for example, an injection.

The invention disclosed in this document may also be employed advantageously in livestock keeping, for example, cattle, sheep, pigs, chickens, and geese. Suitable formulations may be administered orally to the animals with the drinking water or feed. The dosages and formulations that are suitable depend on the species.

In particular, the compounds of the present invention may effectively control a variety of undesirable insects and fungi that infect useful plant crops. Activity may be demonstrated for a variety of fungi, including those causing following the following plant diseases: Anthracnose of Cucumber (Colletotrichum lagenarium); Powdery Mildew of Cucumber (Erysiphe spp.); Glume Blotch of Wheat (Septoria nodorum); Downy Mildew of Cucumber (Pseudoperonospora cubensis); Rice Blast (Magnaporthe grisea); Brown Rust of Wheat (Puccinia recondita tritici); Stripe rust of wheat (Puccinia striiformis); Soybean rust (Phakopspora pachyrhizi); Septoria Blotch of Wheat (Septoria tritici); Apple scab (Venturia inaequalis); Downy mildew of grape (Plasmopara viticola); Powdery mildew of barley (Erysiphe hordei); Powdery mildew of wheat (Erysiphe graminis); Powdery mildew of grape (Uncinula necator); Late blight (Phytophthora infestans); Early blight (Alternaria solani); Peanut leaf spot (Cercospora arachidicola); Net blotch of barley (Pyrenophora teres); Barley scald (Rhynchosporium secalis); Spot blotch of cereals (Cochliobolus sativus); and Maize smut (Ustilago maydis).

Activity may be demonstrated by these compounds on a variety of insects, including Beet Armyworm (Spodoptera exigua), Mosquito (Aedes aegypti), Colorado Potato Beetle (Leptinotarsa decemlineata). Fruit Fly (Drosophila melanogaster), Green peach aphid (Myzus persicae), Cotton aphid (Aphis gossypii), and Bollworm/corn earworm (Helicoverpa zea).

It will be understood by those in the art that the efficacy of the compound on the foregoing fungi and insects establishes the general utility of the compounds as fungicides and insecticides.

Fungicidal Activity

The compounds of the present invention have been found to have significant fungicidal effect, particularly for agricultural use. Many of the compounds are particularly effective for use with agricultural crops and horticultural plants. In particular, the compounds effectively control a variety of undesirable fungi that infect useful plant crops. Activity has been demonstrated for a variety of fungi, including for example the following representative fungi species: Downy Mildew of Cucumber (Pseudoperonospora cubensis—PSPECU), Rice Blast (Magnaporthe grisea-PYRIOR), Brown Rust of Wheat (Puccinia recondita tritici—PUCCRT); Septoria Blotch of Wheat (Septoria tritici—SEPTTR).

It will be understood by those in the art that the efficacy of the compounds against the foregoing fungi establishes the general utility of the compounds as fungicides. The activity of the compounds as effective fungicides was determined by applying the compounds to plants and observing control of fungal disease. The compounds were formulated at 200 ppm in 10 vol. % acetone plus 90 vol. % Triton X water (deionized water 99.99 wt %+0.01 wt % Triton X100), giving a “formulated test compound.” In a few cases, compounds were formulated at 25 or 3 ppm rather than 200 ppm in 10 vol. % acetone plus 90 vol. % Triton X water (deionized water 99.99 wt. %+0.01 wt. % Triton X100), giving a “formulated test compound.” Formulated test compounds were applied to plants using a turn table sprayer fitted with two opposing air atomization nozzles which delivered approximately 1500 L/ha of spray volume.

All plants were inoculated with spores of the fungus the day after treatment, then incubated in an environment conducive to disease development. Disease severity was evaluated 4 to 25 days later, depending on the speed of disease development. The following experiments were performed in the laboratory to determine the fungicidal efficacy of the compounds of the invention.

Leaf Rust of Wheat (Causal Agent Puccinia recondita tritici=Puccinia triticina; Bayer Code PUCCRT):

Wheat plants (variety ‘Yuma’) were grown from seed in a soil-less peat-based potting mixture (Metromix) until the seedlings had a fully expanded first leaf. Each pot contained 3-8 seedlings. These plants were sprayed until wet with the formulated test compounds. On the following day, the leaves were inoculated with an aqueous spore suspension of Puccinia recondita tritici and the plants were kept in high humidity overnight to permit spores to germinate and infect the leaf. The plants were then transferred to a greenhouse until disease developed on untreated control plants.

Cucumber Downy Mildew (Causal Agent Pseudoperonospora cubensis; Bayer Code PSPECU):

Cucumber plants (variety “Bush Champion’ or ‘Bush Pickle Hybrid’) were grown from seed in a soil-less peat-based potting mixture (Metromix) until the first true leaf was 20-80% expanded. Each pot contained 1 seedling. These plants were sprayed until wet with the formulated test compound. On the following day, the leaves were inoculated with an aqueous suspension of downy mildew sporangia and the plants were kept in high humidity for one day to permit sporangia to germinate and infect the leaf. The plants were then incubated in a growth chamber until disease developed on untreated control plants.

Rice Blast (Causal Agent Magnaporthe grisea=Pyricularia Oryzae; Bayer Code PYRIOR):

Rice plants (variety ‘M202’) were grown from seed in a soil-less peat-based potting mixture (Metromix) until the seedlings had a partly to fully expanded second leaf. Each pot contained 5-20 seedlings. These plants were sprayed until wet with the formulated test compound. On the following day, the leaves were inoculated with an aqueous spore suspension of Pyricularia oryzae and the plants were kept in high humidity overnight to permit spores to germinate and infect the leaf. The plants were then transferred to a growth chamber until disease developed on untreated control plants.

Septoria Blotch of Wheat (Causal Agent Septoria tritici; Bayer Code SEPTTR):

Wheat plants (variety ‘Yuma’) were grown from seed in a 50% pasteurized soil/50^(%) soil-less mix until the seedlings had a fully expanded first leaf. Each pot contained 3-10 seedlings. These plants were sprayed until wet with the formulated test compound. On the following day, the leaves were inoculated with an aqueous spore suspension of Septoria tritici and the plants were kept in high humidity (one day in a dark dew chamber followed by three days in a lighted dew chamber) to permit spores to germinate and infect the leaf. The plants were then transferred to a greenhouse until disease developed on untreated control plants.

Table 1 presents the activity of typical compounds of the present invention when evaluated in these experiments. The effectiveness of the test compounds at controlling disease when sprayed on leaves was determined by assessing the severity of disease on treated plants, then converting the severity to percent control based on the level of disease on untreated, inoculated plants.

INSECTICIDAL ACTIVITY

The compounds of the present invention have been found to have insecticidal activity.

Activity may be demonstrated for a variety of insects, including for example the following representative insect species: Beet Armyworm (Spodoptera exigua—LAPHEG); Mosquito (Aedes aegypti—AEDSAE), Fruit Fly (Drosophila melanogaster—DROSME), and Colorado Potato Beetle (Leptinotarsa decemlineata—LPTNDE). It will be understood by those in the art that the efficacy of the compounds against the foregoing insects establishes the general utility of the compounds as insecticides.

The activity of the compounds as effective insecticides was determined by applying the compounds to diet or water, placing insects in the water or on the diet, and observing mortality after an appropriate incubation time. The compounds were formulated at 4000 ppm in DMSO giving a “formulated test compound.” Formulated test compounds were diluted in 96-well plates with acetone:water solutions and applied to species-specific diet or water. The plates were infested and evaluated as described below. Results were averaged over 2-6 replications.

Drosme:

Formulated test compounds were applied to microtiter plates containing fruit fly agar (10% sugar/water) to give a dose of 80 μg test compound/well. Plates were infested by placing at least three flies in each well and sealing the plate. Mortality was evaluated after incubation for two days at room temperature.

Aedsae:

Plates containing formulated test compounds at 6 μg per well were diluted with water containing mosquito larvae. Each well contained at least two larvae. Mortality was evaluated after incubation for three days at room temperature.

Lapheg:

Formulated test compounds were applied to 96-well plates containing Lepidoptera diet at 12 μg per well. Plates were infested by placing at least four fresh armyworm eggs in each well and sealing the plate with cotton batting and plastic. Mortality was evaluated after incubation for seven days at 28° C.

Lptnde:

Formulated test compounds were diluted and sprayed onto leaves of tomato plants. When dry, plant foliage was removed from the plant and placed in 8-well agar trays. Five L2 Colorado potato beetle larvae were placed in each well, and the trays were sealed and incubated at 26° C. Mortality was evaluated after three days.

Table 1 presents the activity of typical compounds of the present invention when evaluated in these experiments. The effectiveness of the test compounds at controlling insects was determined by assessing the mortality in treated test plates, then converting the average mortality to percent control. If any of the three species DROSME, AEDSAE, or LAPHEG was controlled at 80% or more, the compound was considered active (shown as “+” in Table 1). If no species was controlled at 80% or more, the compound was considered inactive (shown as “−” in Table 1).

Synergy Activity

The compound was evaluated in mixtures with pyraclostrobin, or epoxiconazole for protectant and curative activity against wheat leaf rust (Puccinia triticina, PUCCRT), and Septoria blotch (Septoria tritici, SEPTTR). Synergistic interactions were observed for the tested fungicides against wheat leaf rust and Septoria blotch in both curative and protectant evaluations in the greenhouse.

The compound was formulated at six rates (8.1, 2.7, 0.9, 0.3, 0.1, 0.03 ppm) and applied to wheat plants alone and in all combinations of it with pyraclostrobin or epoxiconazole using the methods described in section “Fungicidal Activity” above. Plants were inoculated three days before treatment (3DC) or one day after treatment (1DP), incubated in a greenhouse until disease was expressed, and visually rated (reported as % DC Obs) as described above. The expected control was calculated using the Colby equation (Colby, S. R. Calculation of the synergistic and antagonistic response of herbicide combinations. Weeds 1967 15, 20-22.).

The following equation was used to calculate the expected activity of mixtures containing two active ingredients, A and B:

Expected=A+B−(A×B/100)

A=observed efficacy of active ingredient A at the same concentration as used in the mixture

B=observed efficacy of active ingredient B at the same concentration as used in the mixture

Results are shown in Tables 2 and 3. In both protectant and curative applications, the experimental compound had synergistic activity with pyraclostrobin and epoxiconazole against both wheat leaf rust and wheat leaf blotch.

Animal Health Activity

The compounds of the present invention have been found to have significant potential as anti-parasitics for animal health. Table 4, shown below, presents the activity of typical compounds of the present invention when evaluated in these experiments. Activity has been demonstrated by four out of six compounds screened against Caenorhabditis elegans, a free-living nematode that is an indicator species for animal parasites. It will be understood by those in the art that the efficacy of four compounds against Caenorhabditis elegans, which at 10 μg/mL was equivalent to the commercial anti-parastitic product ivermectin, establishes the potential utility of these compounds to control parasites that attack animals.

The activity of the compounds against Caenorhabditis elegans was determined by dissolving compounds in DMSO, then applying them to petri dishes containing Nematode Growth Medium agar to a final concentration of 10 μg compound per milliliter agar. Escherichia coli bacteria were grown on the plates to provide a food source for the larvae of Caenorhabditis elegans. The bacteria were heat-killed at 65° C. before compounds were added to the plates.

The plates with compound and heat-killed bacteria were infested with 10 microliter drops containing eggs from wild-type Caenorhabditis elegans worms. Adult worms were dissolved in KOH and bleach and washed in Ringers solution to generate the egg suspension. Each compound was screened with approximately 400 eggs, divided between two petri dishes. Egg hatching was evaluated after 24 h at 20° C. Mortality was averaged over the two plates.
